You may have previously seen a balance available for Instant Payouts, but it is no longer there.
When a payment is first received, it is initially reflected as a pending balance in your Dashboard (less any Stripe fees). This balance is available to pay out instantly for up to 24 hours or the creation time of your next scheduled payout, whichever comes first (see Additional Information below).
If an Instant Payout is not manually initiated within that window, those funds are paid out according to your standard payout schedule. Once a standard deposit has been initiated, those funds are no longer available for Instant Payouts and the Instant Payouts balance is updated accordingly. You can monitor the status of your payouts on the Payouts tab of the Dashboard.
For users on a 2-day rolling automatic payout schedule, you might have less than 24 hours to initiate an Instant Payout before your next payout is generated. You can look at the creation time for past payouts to get a sense for when they are generated, or you can move to a manual payout schedule to receive the full 24 hour initiation time.
